Abstract

PROBLEM TO BE SOLVED: To provide a motor which can fix the fixing members of a cover, and a case in a surely sealed state; and to provide a sealing structure which can hermetically fix a pair of assembly members of the cover and the case, or the like. SOLUTION: Outer walls 52 and inner walls 58 are formed on a facing end 44 of a housing 30, which is assembled on an opening end 24 of a yoke 14; and a gasket 50 is disposed between the outer walls 52 and the inner walls 58. Although the outer peripheral parts of a body 66 of the gasket 50 contact with the outer walls 52, the inner peripheral part does not contact with the inner walls 58. However, contacting parts 68 partly formed on the inner peripheral part of the body 66 contact with the inner walls 58. When the gasket 50 is to move, the outer walls 52 interfere with the outer peripheral part of the body 66, and the inner walls 58 interfere with the contacting parts 68. In such an arrangement, movement of the gasket 50 can be restricted.

Here, as described above, in the portion where the contact portion 68 is formed, the contact portion 68 contacts the inner wall 58 and the outer peripheral portion of the main body 66 contacts the outer wall 52.
When disposing the gasket 50 between the inner wall 58 and the inner wall 58, the gasket 50 is pulled outward in the longitudinal direction so that the distance between the contact portions 68 is set to the outer peripheral portion of the curved portion 56, as shown in FIG. It is arranged so as to be wider than the other outer peripheral portion so as to reduce interference between the inner wall 58 and the inner peripheral portion of the gasket 50.

However, the gasket 50 has a main body 66.
Since the outer peripheral part of the outer wall 52 contacts the outer wall 52 and the contact part 68 contacts the curved part 60 of the inner wall 58, when the gasket 50 tries to move, the outer wall 52 interferes with the main body 66 and the curved part 60.
The (inner wall 58) interferes with the contact portion 68, and these outer walls 52
Due to the interference between the inner wall 58 and the inner wall 58, the displacement of the gasket 50 along the rotation radius direction of the shaft 22 is restricted. As a result, the gasket 50 does not slip out of the gasket accommodating portion 48, and therefore, the sealability between the yoke 14 and the housing 30 can be secured and maintained.

Further, as described above, since the inner wall 58 projects toward the one end in the axial direction of the shaft 22 from the opposite end 44 of the housing 30, the height dimension of the inner wall 58 (the projecting dimension from the gasket accommodating portion 48). Is larger than the thickness dimension of the gasket 50. Therefore, the gasket 50 does not ride over the inner wall 58, and the movement of the gasket 50 can be restricted by this, and the yoke 14 and the housing 3 can be controlled.
The sealability with 0 can be secured and maintained.
